Definitions

  • This invention relates to a high speed winding device for textured yarns and, more particularly, to a vertically mounted high speed winding device for parallel plied textured yarns.
  • high winding speed means a yarn speed in the range of from at least 400 meters per minute to about 1000 meters per minute.
  • parallel plied textured yarn means two false twist textured yarn strands, one having "S” twist and the other "Z” twist, for example as produced by a double ended draw texturing process and laid in parallel onto a package.
  • helix angle means the acute angle between the helix or convolution of the yarn and a diametrical plane intersecting the convolution.
  • winding devices known in the art utilize a relatively low speed, full traverse stroke initially, the stroke length being gradually reduced as the yarn package builds in order to produce a package with conical ends.
  • the yarn is laid down on the package at a low helix angle because of the high yarn speed to traverse speed ratio.
  • parallel plied textured yarn wound on a package on such a winding device exhibits an apparent lack of bundle cohesion.
  • French Pat. No. 1,579,444, publication date Aug. 22, 1969 discloses a horizontally mounted winding device for wire in which stroke modulation is achieved by mounting a V-grooved pulley on a full stroke traversing guide to guide the wire onto a spool.
  • the pulley is mounted in a skew position on its axis, i.e., not perpendicular thereto, and the axis of the pulley is parallel to the axis of the spool.
  • a sinusoidal pattern of low amplitude and relatively high frequency is superimposed on the laydown pattern of the low speed full stroke traversing guide.
  • a V-grooved pulley guide similar to that disclosed in French Pat. No. 1,579,444 may be combined with a winding device of the type discussed in aforementioned U.S. Pat. No. 3,730,448 to produce a horizontally mounted winding device that is useful for winding many types of yarns at very high winding speeds.
  • this combination does not provide a vertically mounted winding device for winding yarn at high speeds. Neither does it provide a winding device which will "exercise the yarn" being wound on package as appears to be required to achieve good bundle cohesion in parallel plied textured yarn being wound at high winding speeds.
  • the term "exercise the yarn” means to impart a vibratory motion to parallel plied textured yarn immediately before it is wound on a package, such that the "S" twist and the "Z” twist yarn strands are intermingled to give bundle cohesion to the yarn.
  • the distance travelled by the yarn would remain constant as the V-grooved pulley rotates, no vibratory motion would be imparted to the yarn by the pulley.
  • vibratory motion means repetitive changes in the distance travelled by the yarn which occur at a high frequency and result in a high frequency variation in the tension of the yarn.
  • the present invention provides a vertically mounted high speed winding device for parallel plied textured yarn comprising
  • a vertical friction roller driven at a constant high speed and adapted to rotate a package by surface contact
  • a traversing mechanism embodying an L-shaped lever rotatably attached at its apex to a layrail, the layrail being adapted to reciprocate longitudinally of the package at a constant stroke length;
  • the other arm of the L-shaped lever being pivotably connected to a slide block slidable in a U-track, the U-track being pivotable about a horizontal axis;
  • cam means for changing the angular position of the U-track with increasing package diameter for the producting of conical ended packages
  • the traverse modulating yarn guide being adapted to impart a vibratory motion and a sinusoidal pattern to the yarn being wound on the package.
  • the cam means for changing the angular position of the U-track with increasing package diameter is attached to one of two chuck arms which carry the package and the cam transmits the movement of the chuck arm to the U-track through a cam follower and a lever arm.
  • the cam means for changing the angular position of the U-track with increasing package diameter is driven by a stepping motor and the cam acts on a pin positioned on the U-track to change the angular position thereof.
  • the traverse modulating yarn guide is an eccentrically mounted rotatable disc which is rotated by the travelling yarn.
  • FIG. 1 is a schematic view of one embodiment of the present invention (with parts removed for clarity) in which the effective stroke length is reduced as the package diameter increases by means of mechanical linkages which sense the package build up;
  • FIG. 2 is a fragmentary view of the embodiment of FIG. 1 showing the U-track in position for maximum stroke with the layrail and the traverse modulating yarn guide depicted (for ease of understanding) in both their highest and their lowest positions;
  • FIG. 3 is a fragmentary view of the embodiment of FIG. 1 showing the U-track in position for minimum stroke with the layrail and the traverse modulating yarn guide again depicted (for ease of understanding) in both their highest and their lowest positions;
  • FIG. 4 is a schematic view of another embodiment of the present invention (with parts removed for clarity) in which the effective stroke length is reduced over a period of time by means of a cam driven by a stepping motor.
  • FIG. 1 shows a yarn tube 10 on which a package 11 is built during winding.
  • the yarn tube 10 is carried by spring loaded chuck arms 12 and 13 which are mounted on shaft 14.
  • Shaft 14 is free to rotate such that chuck arms 12 and 13 can be deflected about its axis as the package diameter increases.
  • the package 11 is driven at a high constant speed by a friction roller 15 against which it is held by chuck arms 12 and 13.
  • the friction roller 15 is driven by a belt (not shown).
  • Traversing mechanism 16 is provided to guide the yarn to be wound, onto the surface of friction roll 15 which in turn deposits it on package 11.
  • Traversing mechanism 16 (see also FIGS. 2 and 3) comprises a traverse modulating yarn guide, depicted in this embodiment as an essecntrically mounted rotatable disc 17 arranged on one end of an L-shaped lever 18 by which it is reciprocated longitudinally of the yarn tube 10.
  • the L-shaped lever 18 is rotatably attached by a pin 19 to a layrail 20 which extends over the entire length of the machine and is common to all the L-shaped levers on one side of the machine.
  • Layrail 20 is driven with respect to machine frame 10a to reciprocate longitudinally of the yarn tube 10 at a constant stroke length.
  • U-track 22 Arranged on the other end of L-shaped lever 18 there is a slide block 21 which is guided in U-track 22 in such a way that, during reciprocation of layrail 20, it can slide to and fro in it.
  • U-track 22 is pivotable about pin 23.
  • the bottom end of U-track 22 is attached by pin 24 to lever arm 25.
  • the other end of lever arm 25 is connected by pin 26 to one end of an L-shaped cam follower 27.
  • a vertical pin 28 in the apex of L-shaped cam follower 27 allows the cam follower 27 to rotate in a horizontal plane.
  • the other end of cam follower 27 rests against a cam 29 which is attached to chuck arm 13.
  • U-track 22 The upper end of U-track 22 is engaged by a spring 30 anchored in the machine frame 10a.
  • Spring 30 attempts to rotate U-track 22 about pin 23, which in turn pulls on lever arm 25 and keeps the cam follower 27 firmly pressed against cam 29.
  • yarn preferably parallel plied textured yarn for example, such yarn obtained directly from a double ended draw texturing process, travels part way round eccentrically mounted rotatable disc 17, part way around friction roll 15 and is wound up on yarn tube 10 as a package 11.
  • Chuck arms 12 and 13 hold package 11 against friction roller 15 which is rotatably driven at constant speed.
  • Parallel plied textured yarn wound in a package at a high speed on the winding device of the present invention exhibits high bundle cohesion and thus may be fed satisfactorily directly from the package to a knitting machine.
  • the good take-off characteristics of parallel plied textured yarn from packages produced on the winding device of the present invention has made superfluous the separate ply twisting operation often used heretofor in the winding of such yarn.
